Answer:
-5, multiplicity 3; +9, multiplicity 2; -1
Step-by-step explanation:
The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.
f(x) = (x+5)^3(x-9)^2(x+1) has roots ...
- -5 with multiplicity 3
- +9 with multiplicity 2
- -1
The answer is, -7.4. :) Originally how it came out to be was -7.416198487. So as long as you're rounding up, since the one is below five then the 4 shall remain the same.
Hope I helped out! Good luck
Answer:
Step-by-step explanation:
The general formula for slope-intercept form is y = mx + b
We can see that m (slope) equals 1/3 here. We can also see that the y-intercept (b) is -2. Another way to find the y intercept is to make x equal to 0. You get 0 - 2 which equals -2
Note:
If youre ever asked for the x-intercept, make y equal to zero and solve for x.
Simply the expression which is 30
Answer:
The answer D) because you add the same variable's which leave you with 2x-4
Step-by-step explanation:
first do positive 7-4-1=2. after that do the variables which get you 2x+1x+1x=4x
